In reply to the info that you have sent. I found that the property that was listed in Mary's will was originally listed to John Lorentz. Evidently it was being sold by the sheriff to a family named Detrich and the in a few days it was sold back to Mary.I found numerous references to the same property throughout the Lancaster deed books. We don't know how Johan Casper fits in just yet.We assumed he was Mary's spouse. but the new info indicates otherwise.i will be doing more digging.
